Response redirection in GIOP/IIOP

We have configured a virtual server on port 2007 and the application are using the protocols IIOP/GIOP.After the first response from the server the clients are directly connecting to the servers as the response packet the hostname of the server is mentioned. Can we change this response back to the dns entry of the F5 VIP.

  • Sounds like the perfect job for the Stream feature. You can use a Profile or an iRule to do this, specifying the wrong hostname as the search string and the correct one as the replacement string. I'd got for the iRule myself. Strangely I can't find an example that doesn't use HTTP nor any details on what events might be valid. However, my VE certainly accepts this;

    
    You must assign a Stream profile (with no source or target strings 
    specified) to the Virtual Server before you can use this iRule
    Escape periods with a backslash where possible
    
    The stream expression must always come before stream is enabled
    
    when CLIENT_DATA {
     We don’t want to rewrite requests, only responses
     STREAM::disable
    }
    
    when SERVER_DATA {
      Search for instances of wronghost and replace with righthost
     @ Is a delimiter at the start and end of each string
     STREAM::expression {@wronghost@righthost@}
    
     Apply and rewrite response data
     STREAM::enable
    }
